7 Claims.

This invention relates to automatic fluid filling means for receptacles or containers.

An object of the invention is to provide an improved mechanism partially contained in a receptacle or container which is to be filled with a fluid or liquid, and partially contained in the filling nozzle connected with the fluid or liquid storage tank or drum, said mechanisms cooperating when connected together to fill the receptacle or container with the fluid or liquid from said storage tank or drum, and to automatically stop and cut off the flow of fluid or liquid from the tank or drum when said receptacle or container has been filled to a predetermined level.

Another object of the invention is to provide an improved automatic float controlled means for cutting off the flow of a fluid or liquid from a storage tank or drum to a portable receptacle or container when the same has been filled.

A further object of the invention is to provide an improved spring closed valve construction and automatically operated float controlled operating means therefor, which will open said valve to permit the flow of the fluid or liquid from a storage tank or drum into a receptacle or container as soon as the same is connected with said spring closed valve, and said float controlled operating means automatically disengaging the valve from the container or receptacle and shutting off the spring closed valve when the receptacle or container has been completely filled.

Another object of the invention is to provide an improved automatically float operated controlled spring closed valve mechanism which will be highly efficient in operation and relatively inexpensive to manufacture and produce.

Other objects will appear as the description proceeds.

In the accompanying drawings which form a part of this application,

Figure 1 is a side elevation showing a portion of a storage tank or drum and a receptacle or container about to be filled, the same having the subject matter of the instant invention incorporated therein;

Figure 2 is a plan view of the receptacle or container;

Figure 3 is a sectional view taken on the line 3-3 of Figure 2, and

Figure 4 is a sectional view taken on the line 4-4 of Figure 3.

Like characters of reference are used throughout the following specification and the accompanying drawings to designate corresponding parts.

In carrying out the invention, there is provided a fluid or liquid storage tank or drum I having a filling hose '2, and a tubular valve housing and spout 3 attached to the outer end of said hose by means of the laterally extending pipe connection 4 connected with the valve housing and received in the outer end of said hose, being fastened and secured in place by means of the hose clamp 5 placed about the end of said hose 2.

A transversely extending wall 6 is formed between the valve housing and the spout, and is apertured to provide the bevelled valve seat I of annular form, on which the bevelled valve 8 is adapted to seat when closed. The valve 8 is formed with an upwardly extending shank 9, about which the coil tensioning spring I0 is positicned, with its opposite ends engaging the top surface of the valve 8 and the undersurface of the screw threaded closure head I! for the valve housing 3. A centrally positioned recess [2 is formed in the bottom of the valve 8 for purposes hereinafter described. The spout is open at its lower end and is apertured at l3 in one side thereof.

The receptacle or container 14 is of the usual five-gallon oil can type, having a pouring spout l5, and a top It which is apertured at the opposite side from said spout to receive and support the cylindrical spout guide ll which is open at its upper end to receive the filling spout 3 on the end of the filling hose 2.

Oppositely disposed clamping brackets l8 and I9 are secured about the upper and lower ends of the spout guide I1, and are riveted to the adjacent inner wall of said receptacle or container I4 by means of the rivets 20.

The clamping bracket I9 is formed with a closed bottom 2| underlying the spout guide I1, and axially supports the vertically extending valve actuating finger or rod 22, which is adapted to seat in the recess H2 in the lower surface of the valve 8 to raise the same off of its seat against the tension or pressure of the coil spring l9 when the filling spout 3 is inserted in the spout guide cylinder ll.

An upwardly extending yoke member 33 will be secured to the arm 39 to extend-through-the-receptacle or container top l6, whereby the mechanism may be manually operated to cut ofi the flow of liquid or fluid into said receptacle or'cont'ain'er Id at any desired time beforedt is fulL and. auto.- matically cut off by the hereinbefore described mechanism.

From the foregoing description, it will be seen that-themode of operationzwill be Fae-follows:

The; filling spout: 3: will: beinserte'd within" the cylindrical spout guide likand forced downwardly therein until'thepivot'edzdog movesiinwardly and the nosethereofi engages .initheside slot or? aper- ISIin said filling spout 3, thereby locking the partstogether; Astheifilling spoutB moves downvmrdlyin' the spoutguidexllthe upper end 3 of the vertically extending valveactuating finger 01' rod 22 will engage in the :recess l2 in the undersurface of the valve.8 to force the same open against the tension of'the coil spring 10, thereby permitting the flow ofthe liq'uid or fluid from said storagetank: or drum intothe container it. As the fluid orliquid reaches'apoint near the top or the container l", the'float 3| will become irnmersed in the. fluid or liquid and will rise with the fiuidtocause the arm 32' engaged behind the spout releasing ear 261:0 retract the pivoted dog 23 away from the-spout-guideand' spout and out of thesideaperture l3 in the spout; thereby permitting the spring ltwhicli was-compressed to force the valve downwar-dlyto again seat and also in so doing, forcing the spout 3 upwardly from said spout guidel'i, whereupon the same may be removed from the container l4, and'said filledcontainer moved-'to'any desired location.

While the preferred embodiment of the instant invention has been illustrated and described; it

will'be understood that. it is notintend'ed to limit the scope of the invention thereto, as'many minor changes in detail of construction may be-resorted ism-without departure from the spirit of the inven- 'tion.

Having thus described my invention what I claim as new and desire-to secure by Letters Patent of theUnited states is:
